This updates my ErgoDox EZ layout to v1.3, which has the following
noteworthy changes:
* Added support for logging keys, by pressing `LEAD d`. Also included is
a tool to generate a **heatmap** out of the logs.
* The arrow and navigation keys were rearranged again, and now require
an additional key being held to activate. See the **base layer** for
an image that shows where arrows are.
* The **experimental** layer has been redone, and is now
called **ADORE**, and as such, can be enabled by `LEAD a` now.
* Switching between Dvorak and ADORE is now persisted into EEPROM, and
survives a reboot.
